Leners Patent No.'11o,o71, dated December 13, 187e IMPROVEMENT INCOMBINED LOCKS AND LATCHES.

The Schedule referred to in these Letters Patent and making parl: ofthesame.

To all whom it may concern.-

Be it known that AI, FRANCIS' M. RANoUs, `of Yreka City, in the countyof 'Siskiyou and State of California, have invented a new and usefulImprovement -in Combined Lock and Latch; and I do hereby declare thatthe following is 'a full, clear, and exact description thereof, whichwill enable othrsskilled in the art to make and use the saine, referencebeing had to the accompanying drawing forming part of thisspecification.

Figure 1 isa side view of my improved lock and latch, the inner plate ofthe lock-case being removed.

Figure '2 is a detail sectional view of the same, taken through the linea: x, fig. 1.

Figine 3 is a detail view of the catch.

Similar letters of refcrenceindicate corresponding parts. y My inventionhas for its object toimprove the construction of my improved gate-latchpatented October 26, 1869, aud numbered 96,147, so as to makeit moreconvenient .in use and more effective in operation, enabling it to beused in eithera lock or latch and It consists in the construction andcombination of various parts, as hereiuaftermore fully described.

A is the case of the lock, which is secured to the door by screws in theordinary J4ina-nner.

' iBv is the inner plate of the case A, which is secured in .place by ascrew passing through it -and screwing into the stud al formed uponthe,l case A.

g ,C is the sliding latch, the forward part of' which passes out througha slot in the forward end ange of the case Af.I

'.lhe forward 'end of the latch C has a downwardlyprojecting shoulder orhook formed upon it, which is notched upon its inner edge close to thebody. of the latch, as shown in fig. 1, forming a projection, c', whichenters -a hole, d', in the neck of the double-inclined catch D. 1 l Thecatch D is beveled or inclined upon its upper and inner sides, so thatwhen the door or gate is swung shut the said catch may raise the forwardend of the latch'C, and at-thc same time draw it outward, bringing itinto proper position for the projection c' of the said hook-latch C tobe drawn into the hole df of the catch'D'.l l l E is the spindle, to theends of whichthe knobs F are attached in the ordinary manner.

G is the hub', through which the spindle E passes, and by means of whichthe knob-spindle is enabled to operate the latch C.

In the rear vpart of the latch C is formed an oblong hole, C, to receivethe hub G.

'.lh'einner side of the-latchlC, at the sides of the hole c, is notchedVor recessed, to form shoulders for the cams or arms g of the hub G topress againstin operating the latch, said notch or recess being made ofsuch a length that, when the lower cam or arm gf has pushed the latch Cforward sufficiently .`ar, the

upper cam or arr-'n g' may strike against lthe shoulder is connectedwith the case A, as shown in figs. 1 and 2.

By this arrangement the same spring I will draw the latch back, and atthe same time draw and hold the forwardend of said latch down.

Upon the forward edge ofthe lower or outer end of the arm H is formed ahook or shoulder, h', to receive the stop J which locks the latch, bypreventing, when -in the positions shown in the drawing, the latch-j()vfrom being drawn back to unlatch the door or gate;

The stop J is pivoted to a pin, K, attached to the plate of the case A.A

To the outer end of pin K, upon the outer sidev of the plate of the caseA, is pivoted a disk, L, provided with .a thumb-piece, knob, or otherhandle, M, to enable it to be conveniently operated.

Io the disk L is attached a pinN, which passes in through a curved slot,c2, in the plate of' the c ase A, the said curved slot u being madeofsuch alength as to limit the movementof the stop J.

In the inner plate B ofthe case A, -directly opposite theinwardly-projecting end of' the pin K, is formed a .key-hole, b', toallow a key to be inserted from the outside of the door, to unlock thelatch when required..

The outer edge of the stop J is notched around the pivoting-pin K, toadapt it to receive a key, and t0 allow theguard of the said keytostrike against the body of the said stop, and thus operate-it." Havingthus described my invention,

lI claim as new and desire to secure by Letters .Patent g The pivotedstop J, pivoting-pin K, pivoted disk L, provided witha thumb-piece,knob, or handle M,piu N, and curved slot az in the plate `B of the caseA, in' combination with thearm H h of the sliding hooklatch C c',substantially as herein shown and described,- and for the purpose setforth.
